NOTE: In all cases, the correct fluid level is es-
tablished by checking at the fill opening.
7. Operate the engine for five minutes after filling
the transmission, then check the fluid level again.
8. Clean the fill plug, then install it in the transmis-
sion. Tighten the plug as follows:
• For an Eaton Fuller transmission with a
plug with 3/4-inch pipe threads, tighten the
plug 25 to 35 lbf·ft (34 to 48 N·m).
• For an Eaton Fuller transmission with a
plug with 1-1/4-inch pipe threads, tighten
the plug 60 to 75 lbf·ft (81 to 102 N·m).
9. Operate the vehicle to check for correct opera-
tion.

Level Inspection
NOTICE
Operating a transmission with the fluid level
higher or lower than recommended can result in
transmission damage. Do not overfill the transmis-
sion. Overfilling will force fluid out of the case
through the main shaft openings.
Do not mix types or brands of fluid, because of
possible incompatibility. Do not use fluid addi-
tives, friction modifiers, extreme-pressure gear
fluids, or multiviscosity lubricants.
With the transmission at operating temperature, and
the vehicle on a level surface, check the fluid level in
the transmission.
Some transmissions are equipped with a sight glass
for checking the fluid level. For transmissions not so
equipped, check the fluid level at the fill plug.

Checking at the Fill Plug

1. Clean the area around the fill plug, and remove it
from the side of the gear case.
2. Using your finger or a bent pipe cleaner, see if
the fluid is level with the fill opening. See
3. If the fluid level is low, check the transmission for
leaks, and correct as needed.
4. If needed, add the recommended fluid, until it is
level with the lower edge of the fill opening. See
Table 3 for approved transmission lubricants.
5. Clean the fill plug, then install it. Tighten the plug
as follows:
• For an Eaton Fuller transmission with a
plug with 3/4-inch pipe threads, tighten the
plug 25 to 35 lbf·ft (34 to 48 N·m).
• For an Eaton Fuller transmission with a
plug with 1-1/4-inch pipe threads, tighten
the plug 60 to 75 lbf·ft (81 to 102 N·m).

Checking With the Sight Glass

If the transmission is equipped with a sight glass,
check the fluid level as follows:
